There was a thread about this a while ago. I for one did some simple research on this hypothesis, and the easy conclusion I reached was that it's B.S.

The acceptance of authority does not lead to intelligence.
A mind untouched by thought...the end of knowledge.
To see reality loose your opinions.

Interesting. It should be pretty obvious earth has always been growing, because we've being constantly hit by space rubble, albeit smaller mostly but there. Piles up and doesn't really go away. But it was news to me that earth's size has doubled since 65 million years ago. Pretty fast growth, we might one day be Jupiter-size, though it takes time. That kinda gravitational pressure would make whatever life might still be there, evolve to be stronger than us, but I wonder how it would affect their lifespan and thinking, would being stronger equate to increased adrenaline and aggression?

I know nothing bout tectonic plates though, xcept what school told me.

Can you imagine? Can you choose?

  • I tried to enter my favorite quote but the data limit was breached so you get this. Pretty anti-climatic isn't it?

Im just curious if earth was half the size 65 million years ago would there have even been enough gravity to keep its atmosphere?
From wikipedia:
An atmosphere (New Latin atmosphaera, created in the 17th century from Greek ἀτμός [atmos] "vapor"[1] and σφαῖρα [sphaira] "sphere"[2]) is a layer of gases surrounding a material body of sufficient mass[3] that is held in place by the gravity of the body. An atmosphere is more likely to be retained if the gravity is high and the atmosphere's temperature is low.
I think thats one of the reasons Mars wasnt able to sustain a decent atmosphere itself and hence the reason its a dead planet today.

The problem here is that the Earth is apparently growing from nothing! Is the Earth taking surface mass from its interior? No, because then the Earths interior would be largely hallow. We know it isn't because we still have volcanic activity, which requires large quantities of heat and pressure in which a hallow Earth cannot provide. Matter collected from space debris would be rather insignificant compaired to the total mass needed to support such growth, basically the equivalent of you doubling yoyr size with the mass of a hair. Thus we can conclude that the Earth is not growing in such a way because it doesn't have the mass to do so.


Something I've noticed a lot with fringe theories is that they always fail the basics.

I reject your reality, and substitute my own! Mostly because yours is boring as hell.

Just two replies ago I mentioned the space rubble flying on us constantly. It's small, yes, but does it somehow leave earth? No.

Unless volcanoes shoot it high enough off the air. There was a stuff about space rubble constantly hitting us in a finnish science magazine, some argentinan research place where they register the frequency of space rubble showed results it being pretty constant. It might burn to fragments in the atmosphere, but those fragments still reach us.

And I addressed that issue say specifically that the accumulated mass of such debris is insignificant in total comparison to the Earth. In fact the majority of such matter vaporizes into gas becoming part of our atmosphere, thus never adding its mass to the Earth itself.

But does that gas leave earth and not come back? If not, then we'd have a very gassy planet like Venus, but no. So the gas either leaves the earth or comes back down eventually.

And you should really read the study about how much matter actually manages to rain down to earth? They register it every minute, the sensors on ground level, maybe every second. That goes on thousands, millions of years. If those particles cannot be pushed outside earth's atmosphere by volcanoes or anything else, it will keep growing. Will some force pull those molecules out of the atmosphere, outside earth into space? Like a comet that passes by?

Ok, basic atmoshperics 101. One of the primary gases of our atmosphere is hydrogen. Hydrogen on its own is actually light enough to escape our atmosphere, and in fact does so at a rate of approximately 95,000 tonnes per year. Helium, being slightly heavier escapes at a rate of approximately 1,600 tonnes per year. Have no fear as this amounts to about. 000000000001% of the total atmospheric mass, so it would take trillions of years for it all to escape naturally. Of course by then the sun will have expanded and destroyed the Earth by then.

Getting back to the main topic. The estimated mass of yearly star dust hitting Earth is about 41,000 tonnes. Sounds like a lot right? However the total mass of the Earth is about 5.97219 × 10^24 kg.

Or

5,972,190,000,000,000,000,000,000 kg

If you know anything about percentages you could see that the star dust fall is not only insuffecient to double the size of the Earth in the time frame the video showed, but laughably so.

You know you are showing off a good deal of ignorance.  Incoming matter is not just small, but compared to the planet it is microscopic.  It would take billions of years for it to effect the earth's mass by even a fraction of a percent.

Absolute spectacular rubbish. Plate tectonics is an observable phenomena across the whole of the atlantic and on the pacific rim.

Answer the simple question - where did all the extra material come from ??

Mind blowing.

I think maybe the gullibility people have to this sort of thing derives from ignorance, not any foolishness.  In this case it is just not comprehending the real size of the planet, and of course not understanding plate tectonics.
